In the factory, the nozzle centre is set at the centre of the
nozzle plate. If it becomes necessary, however, to correct the
nozzle centre (e.g. exchange of the injection unit), observe
the following steps:
1. Measure the deviation of the nozzle centre from the diameter
of the eccentric ring both horizontally and vertically.
2. Loosen the cheese head screws (Item 1; 3x) of the
connecting pins (Item 2). First correct the horizontal deviation
by adjusting the nut (Item 3) on one of the two lower connecting
pins; then correct the vertical deviation by adjusting the nut on
the upper connecting pin.
3. Tighten cheese head screws (Item 1; 3x) (maximum
tightening torque: 250-400 Nm; 340-540 ft lb). Admissible
deviation: +/- 0.2 mm (0.008 in.) of nut offset.
